Study On Chemical Reaction Of C-P Bond Of Phosphirane Complexes

Phosphiranes splitted into phosphinidene under high temperature,but so far,there are only a few examples to explain this chemistry.We decided to investigate the thermolysis of phosphirane complexes.we found 1-H-phosphirane tungsten complex produce ethylphosphinidene complex [?CO?₅W-P-CH₂CH₃],1-esterphosphirane complex cleavage to esterphosphinidene complex [?CO?₅W-P-COOCH₃].however,1-acylphosphirane complex led to the simple decomplexation of the ring.whereas,1-acyl-2-phenylphosphirane complexes can not only produce phosphinidene,but also led us to the discovery of the phosphorus analogue of the Cloke-Wilson rearrangement.
